So I'm currently on my second Captivate after my first one seemed to have terrible battery life (couldn't even last me a full work day). The new one i have doesnt seem to be all that much better. The two phones just seem to drain so much battery in idle and i just could not put my finger on what the problem may be. At first, I thought it may be an app I had, so i restored my phone to factory settings, but still it seemed to drain a lot in idle. So for the last three nights, I tried sleeping with my phone unplugged to see how much it would drain. I slept just about 6 hours each night.
1st night i had it in airplane mode - 12%.
2nd night with 3g on and wifi off - 12%.
3rd night with just 2g on - 0%.
so my question is: why would my phone drain the same amount in airplane mode as with 3g on but with 2g on the battery drain is nothing?? Is everyone else getting similar battery drains trough the night?
I only have a week before my 30 day return period is over and I would hate to have to return this phone. If anyone can help me out this week and leave their phone unplugged through the night using the configurations i had and share their results, it would be greatly appreciated.
Grab system panel from the market. The paid version lets you monitor the phone. Well worth it with these issues.
What firmware are you running? When I had jf6 I had these battery issues. Ever since I flashed jh3 my battery lasts forever. The other day I got about 30 hours before I needed a recharge

My battery didn't last long with the jf6 firmware, but jh2 improved it greatly!! If you don't have jh2 yet, flash your phone to it and then do your tests again.

I am still using jf6 firmware, as I was skeptical of the gps logging issues some were having, but I was able to fix (significantly improve) my battery life issues with an app called Juice defender, look it up in the market if you don't want to flash a non-official firmware...

I'm still using the stock firmware. what exactly are JH2 and JH3? i know they are updated firmwares but are they from samsung or custom? how do i go about flashing those roms? What issues do those firmware address?
Sorry for the noob questions, but this is my first android phone and i want to know everything i can before diving into rooting and everything.
I really just wanted to know if the issues with my battery are typical of other captivates as the two that i have had seem to have similar battery life (which wasnt that great). So everyone just thinks this is a firmware issue and will be solved by flashing JH2 or JH3?
ok so here's the deal.. my phone has been off the charger for about 4 hours and im already down to 40% left. I live in a 4g area but it is spotty in many areas, including my workplace. I have gps (for weather updates and nav, when i need it) and wifi on at all times. i am running the EP4P modems on GummyCharged Froyo ROM 2.0. I have the screen brightness turned all the way down. No overclocking.
Kernel: 2.6.32.9 [email protected] #30
I have tried several different methods to calibrate the battery but it doesnt seem to help. When i'm at home and using wifi the battery life is pretty good. so is it my modem? the ROM? my kernel? Can anyone help me get the most out of my phone? I've tried various modems but have stuck with GC since I loaded it back in sept.
If you are in a spotty area, that can happen. Searching for signal and 4G/3G switching can drain the battery very fast. I would try putting the phone in cdma mode while you are at work or any other spotty area.
Turn off wifi and gps if you are not currently using them, wifi scans for networks regularly and you may have apps/widgets that are using the gps/ network location services while you are idle
also, my battery stats say that display is using up 45% (as of now) of my battery life with 23 mins of usage time. I have the wifi turned on for my convenience, but it doesn't scan for networks as i've turned that function off. I will try the cdma switch, but I have also tried that before and I don't think it makes too much of a difference.

The battery usage metrics aren't useful until you've been up for several hours. And having the screen using a high percentage is ideal -- it means that the rest of the system is throttling like it is supposed to.
How long have you been on GummyCharged? A few weeks into having that on my phone happily, battery life took a nose dive similar to what you are experiencing. I flashed back to stock and battery life is much better. Waiting for official GB before trying another ROM.

i see your point but im now at 5 hours uptime with 23% battery left.. light/medium usage. display still says 46% battery use with 25 mins of usage time. that seems like incredibly too much battery drainage.
also, when i put the phone into cdma mode do i select the home or automatic option, and what is the difference?

i flashed GC onto my phone in mid september. since then i've tried calibrating the battery several times. a totally futile exercise it seems. What setup are you running now? 2.2.1 with EE4 modem? Rooted?
The only thing that has solved my battery problems is juice defender. Sitting idle for eight plus hours at night I only drop about 3-5%. Of choose it still drains just as quickly while using the phone but it will help if you're in a spotty area because data is turned off if your screen is off.

I have similar issues. After rooting and flashing Humble on my phone, my battery life sucked, much much worse than stock.
I then put the standard 2.3.6 on it and it still sucks. Full 4G all day, barely use it.
It's sat on my desk at work all day today. Sent a few texts. I've installed betterybatterystats and nothing is taking up a large portion of partial wakelocks.
Really don't understand how people are getting such good numbers...
I find that by far and away the best way to increase battery life is to lock my phone in 3G unless I am downloading something & want the 4G speed.
I have a home screen widget that turns 4G on/off & only turn on 4G occasionally. I do not leave WiFi on although I leave GPS on at all times & find that uses almost no battery life whatever.

I thought my battery was bad then i looked at that graph. I don't even get it... The screen is mostly off and the signal is green most of the time.
It may be some rogue app on your phone. Backup your apps and do a factory reset. If your battery life significantly improves, restore your apps one by one and find the culprit.

Just stock EE4, unrooted, will do OTA as soon as I get the notification. Battery life is not that good, I can get 14 or so hours of use leaving it on 3G most of the time, but on Gummy I would get 50+% drain just having it sit overnight. Now leaving it sit overnight doesn't kill it.

you prob shouldnt be using that ROM..its kinda outdated...just flash the new ALL IN ONE ODIN of EP4D...my battery life is pretty sick...i left it unplugged all night and saw a tiny drop..my phone was connected via wifi tho..if my phone is in 4g the battery loses pretty quickly or if my screen is on ultra bright..
I'm running the stock, rooted, manually-debloated EP4P and I've been getting downright stellar battery life.
My kids watched an hour of Netflix this morning while getting ready, and now (almost 10 hours later), I'm still at 63%.
But! (and here's the kicker) - I leave WiFi on all the time (I'm contemplating buying Woofi to save even more battery when I'm not at home or work) and have my WiFi sleep policy set to "Never".
This is (one of) the key(s). It doesn't matter how strong your 3G or 4G signal is, WiFi will always save you battery. 3G is less battery intensive per-time, but much more battery intensive per-byte. 4G is less battery intensive per-byte, but much more battery intensive per-time. WiFi is much more battery intensive per-time, but wildly less battery intensive per-byte.
In other words, for the same download, you'll use the least battery on WiFi (even with a slower than LTE connection), 4g in the middle, and 3G the most.

is there an odin file for what you have or did you do the manually debloating after rooting?
I have seen a small improvement by charging before I go to bed, unplugging it from the wall and leave the phone on during the night with WIFI on and no apps running.
When I do that, and wake up in the morning, the battery is still at 100% and I can get a good day with heavy use, and a day and a half with moderate use easily.
However, last night, I needed the phone to be on as I was on call for work this morning so I charged it and then unplugged. But turned WIFI off as I did not want whatsapp msgs to disturb.
No apps were running, and the signal is just as strong as always (which isn't great but is is the same as always), but when I woke up after 8 hours, the battery has completely drained overnight to an alarming 12%!!
When I looked to see what was using the battery, Cell Standby has used 39% and Phone Idle 40%, the screen was only on for 3mins during that time.
My settings for apps are that they only sync manually or when opened, so nothing was running.
When I looked at the awake time, it shows that the phone has not been awake.
So I cannot understand why by turning WIFI off, the phone will drain overnight!
In a normal day Cell Standby and Phone Idle contribute very little to the battery usage in my case, but I just can't understand what has caused this to happen.
Any help appreciated, as I am quite alarmed thinking that my battery can die overnight when it has not been used.
Thanks
I had the same problem! I left my phone at 100% and turned it off over night. And the next morning it was at 7%!!
Sooooo many problems with the sensation, I am soon change my phone.
In your pictures i can see that you have bad signal. With this bad signal the phone will try to get a better signal all the time and this uses much battery.
Try it over night at a place with better signal and look how much battery it uses. And you can charge to 100% and then wipe batterystats in recovery maybe that helps.

I have similar problem Hi friends,
I use faux123 kernel for 2 weeks + ARHD 4.1.7. All things was good, in sleep time my phone was not do any drain. I meen if the battery was fully charged it was 100% at morning (phone was set to flight mode) and even after starting the phone it was staing at 100% for one hour. And i was get 18 hours for hard working with it.
But it's 2 days it drains so fast. It drain 20% of battery in 5 hour sleep time in flight mode. And i just have 8 hour to work with my phone.
Do you know wath is problem?

Did you install any new apps or changed some settings in an app wich can cause this drain?
Wiped batterystats in recovery?
Did you change the CPUFREQ? Because i think faux kernel is at 1,7GhZ after flashing it. You can use faux clock to change the Kernel settings.

I have always the same signal, it varies from 2 to 4 bar, when I took the screenshot went down to 1 but I normally have a bit more.
So, with the same signal and WIFI on, when I wake up in the morning I still have 100%, this is what I don't get!

Bcuz with your WiFi on the phone is not switching through data signals which uses less battery. I live in a bad signal area. So calls work great but data signal is crappy, goes from 2G to 4G to 2G..so with WiFi on for data there is no need to constantly try to grab a better data signal.

But data was also turned off, and I am only on a 3G network, not 2G available with my carrier.
My point here is that when I go on hols soon I will not be using data as I will be abroad, and WIFI only once a day maybe as I will be out and about.
So from last night's performance, does that mean I will only get 8 hours??
It is weird...
I was getting some insane battery drains my self after flashing the ARHD 3.X.X the one turning the sensation to XE , allthough I had very good signal and my phone fully recharged in the morning was like 61% for uknown reasons then I jumped to ARHD 4.1.7 and since then everything is fine .I don't understand though why some people blame the phone for it.to me it appears to be more like software tweaks and twists related to battery management the sensation is amazing phone I have it for a month and honestly I never regret the day i picked it when I had to make the choice senny or sg2

Is it normal? Newiest Stock ROM.
My Wife's unrooted S2 runing the stock ICS is having issues with battery charge.
She has had it for about 1 month.
The past week she can no longer charge it past 70% (this value is continually dropping). It will go to 100% if the phone is charging while off for 12+hours but then as soon as it turns on the battery drops to 75%.
I have read of pulling the battery for a while, Plug in the phone pop in the battery and power on immediately but this has done nothing.
I have not rooted and tried other roms on her phone yet since we may have to return it.
Any suggestions?
BTW... Sorry for one more battery thread. Just didn't find the solution with my searching.

first open battery usage and investigate which app eat a lot of power.
sometimes just restart the phone will clear out the issue.
The app which eat many power is the browser but I have tried other browsers too but same problem happened.

serious battery problem
OK, I have a serious problem. I updated official RUU, and my phone is running smooth. Battery lasts 1-2 days, everything is working fine. But last night battery was on 17% and I put it to charge at 12pm, woke up at 6am and it was on 33%. I'm charging it right now and it's up to 41% then drops to 39% and so on. Tried another charger - same thing. It won't charge! No new apps, no new settings, battery stats shows the same power use,.... Battery health is good, Auto sync is off,.... I have Go Power Master, Juice Defender, shows no problems. 3G is off, it's on GSM only, Wi-Fi is off, GPS is off and so on, my phone is fully optimised and this happened last night. I charged it while off and now it's on 37%! So I guess it's not a software issue. Anybody has an answer or a clue what could be the problem, please? Is my battery dead (year of use)? Thanks in advance.
try to restart your phone?
Tried that. I'm currently charging it power off, turned it on and it's still draining. While it's off!
i guess it's battery problem. Borrow another battery from your friend and try again.
Well, it was a strange thing... I've noticed that GO Power Master is killing like 25 apps and prolonging time for some 2 and a half hours when you hit optimise button every 2 minutes. So some apps are running in the back and draining the battery. So I uninstalled some of them (clock widget, Noom, Zoner antivirus,...) and restarted phone and by the end of the day it was all stabilised like before. I don't know what happened. I'm still testing it but I've managed to charge it to 100% and there was no drain over night. We'll see.

Noom
I have a S2 and every day, at 20:00 the phone starts a process and gets very hot and also drains the battery.
I discover that if I freeze the Noom app, it doesn't happen.
So, I blame noom for your draining issues and mine.
Does anybody else having this problem?

I didn't had a problem since uninstall, but it happened again later, I think it was from Firefox. While it was on charger, I got popup note saying something like "phone is using more than current can deliver, try to kill some apps or turn phone off while charging." First time I see that note. Probably because it was on Sense, not on launcher. I've noticed that Firefox is using a lot of memory, uninstalled it and it was all normal like before.

I had this problem, but svery time it was solved with rebooting. It showed normal percentage. I think, you just need to reboot device sometimes, may be once in two days. I suppose to think the couse of ghis problem is a kernel) it can be engaged with not an exact process, so battery drains. Try to change kernel, or rom, or battery)
